Comparison of efficacy and safety of percutaneous balloon angioplasty and percutaneous stent implantation in the treatment of central venous stenosis in dialysis patients
Objective To investigate the efficacy and safety of percutaneous balloon angioplasty and percutaneous stent implantation in the treatment of central venous stenosis in dialysis patients.Methods Forty dialysis patients with central venous stenosis admitted in our hospital from January 2019 to January 2021 were selected as the study objects and divided into group A(24 cases)and group B(16 cases)according to different treatment methods.The group A was treated with percutaneous balloon angioplasty,while the group B was added with percutaneous stent implantation.The therapeutic effects of the two groups were compared.Results At 6 and 12 months after operation,the primary patency rate of the group B was higher than that of the group A(P＜0.05);the number of operations per venous cavity of the group B was more than that of the group A,and the primary patency time was shorter than that of the group A(P＜0.05).At 6 and 12 months after operation,the dialysis blood flow and vascular diameter in the group B were greater than those in the group A(P＜0.05).At 6 and 12 months after operation,the levels of fibrinogen(Fg)and D-Dimer(D-D)in the group B were lower than those in the group A(P＜0.05).There was no significant difference in the total incidence of complications between the two groups(P＞0.05).Conclusion In the treatment of central venous stenosis in dialysis patients,compared to simple percutaneous balloon angioplasty,combined with percutaneous stent implantation can help to improve primary patency rate,promote improvement in dialysis blood flow,vascular diameter and coagulation function,and has high safety,which is worth promoting.
